The mother of Simon Carman, the Australian truck driver arrested in Thailand for the alleged murder of a teenager, initially believed news reports and arrest videos were sophisticated AI-generated fakes as part of an online scam. Wendy Carman, 68, expressed her disbelief to her son after seeing footage of his arrest at Bangkok airport.
Carman, 45, was detained after the body of 17-year-old Tunchanok Donhomla was discovered stuffed inside a suitcase found in long grass near railway tracks. CCTV footage had shown Carman riding a scooter with a suitcase strapped to the back shortly before his arrest. He was apprehended at the airport with a boarding pass for a flight to Perth, Australia.
Carman told authorities he was returning to Australia to collect a replacement bank card and intended to come back to Thailand. His passport, phone, and luggage were seized. During a brief period he was allowed to use his phone, he received a message from his mother, who was concerned the news was a scam, a police source indicated.
"Because he was living in Thailand, she just thought it must be AI and all fake," a police source said. The message reportedly prompted Carman to break down, saying, "Even my mum's heard about it." This message, according to Daily Mail police sources, made the reality of his situation sink in. He had previously provided his statement calmly, even when discussing folding the victim's body into the suitcase.
Carman later replied to his mother, confirming the news was true and that he likely would not see his family for a considerable time. He was denied bail by a judge who deemed him a flight risk and was remanded in custody for up to 84 days, the maximum period police can hold a suspect before an indictment is filed. He is currently held in the hospital wing of Pattaya Remand Prison.
He has not requested visits or phone calls and has not retained legal representation, though Australian consular officials are in contact with him and Thai authorities. Police state he has been cooperating with the investigation.
Locals in Pattaya described Carman as a regular in bars and cafes, often buying drinks and offering gifts to young women. He had arrived in Thailand on a student visa in October 2025, though he had made frequent visits for years prior. He was known in the areas surrounding his apartment, with local business owners greeting him daily.
One bar owner, Kate, recounted Carman's frequent visits, noting he would buy drinks and food. She also mentioned his persistent attention towards her 20-year-old niece, who worked as a waitress at the bar, offering her gifts and asking her out. His niece reportedly found his behavior unsettling, and he frequently offered massages to the female staff.
In his statement to detectives, Carman claimed he offered Ms. Donhomla ฿500 (approximately AU$2.15) when she decided to leave his apartment. He alleged that when he showed her his wallet containing around ฿20,000 (AU$870), she pulled out a knife and demanded all the money. Carman stated he panicked, grabbed her wrists, and when she continued to struggle, he placed his hands around her neck, eventually leading to her collapse. He told detectives he hadn't realized how tightly he had been holding her.
Sources close to the investigation suggested Carman claims he forgot to take medication for a nerve condition affecting his brain, which can impair judgment. Photographs show a significant, long-healed scar on the back of his skull. He realized Ms. Donhomla was deceased when she stopped breathing. He then allegedly placed her body in a suitcase, put the knife on his fridge, and went to bed. The body remained in the suitcase in his bathroom for a day, even as the victim's friends arrived at his unit looking for her. The following night, he allegedly transported the suitcase on his motorbike and left it near railway tracks.
Ms. Donhomla's friends reported her missing on Friday, leading to Carman's arrest before her body was found. Police Colonel Anek Sarathongyoo told reporters that a sense of instinct guided the initial stages of the investigation.
Carman faces the possibility of the death penalty or life imprisonment if convicted. Ms. Donhomla's family has stated they will not accept any financial settlement, with her father emphasizing his love for his daughter and his desire for the legal process to conclude. The family has ruled out any deal that could reduce Carman's sentence.
